References

Based on the sculpture,“Twisting Torso” exploring
the human body in motion,
twisting as far as it can
naturally being pushed while
staying directly upright
Form is made up of 9 cubes,
each individual cube
containing five stories

Twists 90 degrees from the
ground level to the top floor

Each floor consists of a
square section around the
core and a triangular part
supported by an external
steel structure
The central core is
supported by a foundation
slab

The corner of each floor is a
concrete column supported
by a pile foundation

STRUCTURE
Introduction

Structural ComponentsStructural Analysis

Construction

References

The structural slab is fitted
around the core
The forms for the structural
slab are triangular shapes,
together forming a floor
The forms were rotated 1.6
degrees for each floor in
order to create the
characteristic twist of the
building

Construction

References The core is the main loadbearing structure
Large concrete pipe, with an
inner diameter of 35ft.
The walls are 8ft. Thick at
the bottom, gradually
shifting to 1ft. thick at the
top
The elevator shafts and
staircases are located inside
the core

CORE
Introduction

Structural Components

Structural Analysis

Construction

References

The steel support is located
on theexterior of the
building, which is linked
together by the spine, acting
as the loading backbone
from the winds
The steel support transfers
shear forces to the
supporting concrete core.
Each steel section of the
spine has to fit precisely in
the one below it

SPINE

References

The system consists of aspine column at the corner
of each floor plus horizontal
and diagonal elements that
reach to each side of the
glazed spine
Stabilizers also connect the
floor slabs with the
framework
